Abstract: Mise en oeuvre de procedes de conversion biologique et chimique qui requierent la presence d'une ou plusieurs substances catalytiquement actives, telles que des enzymes, des micro-organismes, des cellules, des organites, des homogenats de cellules et des catalyseurs organiques et inorganiques. Le procede est execute dans un systeme liquide consistant en au moins deux phases aqueuses (F1, F2) selectionnees de maniere telle que la substance catalytique (K) soit enrichie dans une (F1) des phases, tandis que le substrat de depart (S) du procede est distribue dans les deux phases ou, avantageusement, est enrichi dans la meme phase que la substance catalytique, et le produit du procede (P) est distribue dans les deux phases ou, avantageusement, est enrichi dans l'autre phase (F2). Pendant le procede, le systeme est maintenu en agitation pour disperser finement une phase dans l'autre. Le produit du procede peut etre extrait de l'autre phase, soit en arretant l'agitation du systeme et en laissant les phases se separer, ou en maintenant la dispersion d'une phase dans une partie seulement de l'autre phase et en soutirant en continu la partie superieure de l'autre phase pour en extraire le produit du procede et renvoyer ensuite la partie de phase soutiree vers la partie maintenue en agitation du systeme liquide. Avantageusement, l'autre phase (F2) du systeme liquide presente un volume sensiblement plus important que la phase mentionnee (F1). Ce procede peut etre applique a des substrats de depart gazeux, particulaires, possedant des micro-molecules ou des macro-molecules, pouvant etre solubles ou insolubles dans le systeme.

Abstract: The invention concerns a three- or four -stage gas compressor comprising two interconnecting compression units operated by hydraulic pistons (13, 50); the first unit comprises a central hydraulic section (A) flanked by two identical and symmetrical lateral sections (B, C) each incorporating the first and third stages and operated by an alter-nating hydraulic piston; (13) the second unit comprises a central hydraulic section (D) of lesser diameter than that of unit one but with equal volume of oil, and two lateral (E, F) sections similar to those of unit one but of lesser diameter. In the fourstage embodiment the lateral sections (E, F) of unit two comprise between them the second and four compression stages, whilst in the three-stage embodiment the lateral sections of the second unit comprise only a single section each of the second compression stage. The oil chambers (14, 25) relative to each unit's central section (A, D) interconnect - in either embodiment - by way of a compensating valve (20). For each single stroke of the first compression unit's piston (13) in central section, the corresponding piston (50) in the central section of the second unit completes a contrariwise single stroke: the consumer unit thus receives a delivery of gas per single stroke of the piston (13) in the first unit's said central section (A).
